Typical scenario
Construction of digital media environments, such as, news network, production network, collecting network, broadcasting network and media assets and management network
 

Application background  

Driven by the rapid development of digital business systems, new business platforms have emerged continuously, shifting the focus from business upgrading to system renovation. The integration of the business, storage and security systems has attracted increasing attention of major TV stations. Currently, domestic TV stations have paced up their reconstruction and have completed or are conducting construction of broadcasting, news, production, media assets and management network systems. The expanding systems will evolve the traditional work flows of TV stations based on magnetic tapes. Network data sharing and real-time editing will give a strong boost to TV stations' production efficiency and program quality.

Solution  

The comprehensive TV station storage network system comprises the comprehensive production, news, collecting, advertising, audio and media assets and management networks. Built on the basis of the SOA structure and ideas, the entire system is featured by strong dynamic and flexible scalability. The BWStor series storage products can satisfy varied requirements for storage performance, security, reliability and volume of sub-networks, thus meeting the future development trend.

The storage system of the comprehensive production network comprises BWStor BW3200, as the storage core, optical fiber network and storage devices. By integrating NAS clusters, it provides access interfaces that support various protocols, distributed load balancing, flexible performance and space expansion and automatic configuration adjustment.

The storage system of the news network adopts BWStor BW3200 as the storage core and applies the BWmirror technology to realize the file-level disk array real-time disaster recovery. The system creates data mirror images between disk arrays and enables real-time file-level access. When a disk array fails and cannot be accessed, the mirror image can provide data services without delaying, thus ensuring continuity of front-end applications.

The storage system of the collecting network adopts BWStor CSA5000 as the storage core and supports disk arrays of various brands and types. It can virtually integrate disk arrays of all standards to provide file sharing and storage services. It supports various client operating systems, realizing file and data sharing across different operating systems such as Windows, Linux and MAC.
 
 The advertising network's storage system adopts BWStor BW2000 as the storage core and is constructed based on the IP Ethernet and dual-controllers security redundancy structure. The performance and capacity of the storage devices can be expanded. The embedded BWFS system is highly cost-effective and is compatible with original IP SAN disk arrays.

The audio production network's storage system adopts BWStor BW1000 as the storage core and comprises the server structure and professional storage system. Base on the SAN structure and equipped with the BWFS file system, storage system provides the SAN-based and NAS-based file sharing and storage spaces to meet the demands of small-to-medium-sized audio and video production networks for bandwidth performance and data sharing space.

The media assets and management network's storage system adopts BWStor BW3200 as the storage core and the optical fiber network and out-of-band data transmission structure. Because of the large bandwidth and low delaying of the optical fiber network, the system can meet strict requirements of application platforms for performance. 
 
 

Advantages  

1. The entire network's storage systems are built based on standard storage and access interfaces. Application program platforms can use file sharing and storage spaces directly without secondary development.

2. The storage system is built based on the SOA structure, SAN mode and NAS cluster. Therefore, its devices can be expanded flexibly and dynamically. Through storage volume expansion, the entire system's storage performance can be largely enhanced to meet future business needs and form a private cloud storage system for the comprehensive TV station network.

3. The out-of-band storage mode can separate metadata from physical data. Metadata is transmitted through Ethernet and processed by BWStor storage core. Meanwhile, front-end application servers can access physical data through Ethernet or optical fiber network directly from disk arrays, thus reducing the data request responding time and improving the data transmission speed.

4. The system supports file sharing and storage across Windows, Linux and MAC systems.

5. In addition, it fully supports application software on varied operating systems, including non-linear editing, media assets management and other application software including Autodesk, EDIUS, FCP, AIA, Legend and Telestream developed by overseas leaders.
 

6. The storage products imbedded with BWFS file system feature a strong authority management capability when being used with applications including the Windows domain controlling management server and Linux authority setting.
